High external input agriculture depends heavily on artificial chemical inputs such as fertilisers and pesticides, hybrid seed, mechanisation based on fossil fuels and often also irrigation where developing society may hardly afford.
What is low input agriculture?
“Low-input” is a catchword for what many feel is a primary requirement for economic and environmental sustaina- bility in farming—the need to cut back on purchased off-farm inputs. These especially include synthetic chemical fertilizers and pesticides, but also live- stock growth stimulants.What are advantage of low external input agriculture?
Low-input fields increase carbon sequestration in the soil by storing more carbon,compared to the conventional rice fields. “The LEISA system practices no-till management, which is known to increase soil organic carbon and mimic the process of carbon sequestration,” said Firth.
What are the advantages of Heisa?
The advantages of High External Input Agriculture (HEIA) New improved varieties gave yields within a short period of time. Mechanization solves the problem of Labour shortage. Income and profit margins of the products were increased • Productivity of land increased. Increased market facilities for production.
What are the advantages of Leisa?
In areas with a low production potential, LEISA can stabilize and restore the carrying capacity, but generally has limited potential to improve socioeconomic conditions for growing populations, and an increased production may also result from a further depletion of natural resources, and by a limited number of farmers.
What is high yield farming?
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. … The higher the yield and more intensive use of the farmland, the higher the productivity and profitability of a farm; this increases the well-being of farming families.What is input system in agriculture?
Agricultural inputs are defined as products permitted for use in organic farming. These include feedstuffs, fertilizers and permitted plant protection products as well as cleaning agents and additives used in food production.
What is cropping index?Cropping index refers to the times of sequential crop planting in the same arable land in one year, usually defined as the ratio of the total seeding area to the arable land area (Liu, 1993), which reflects the using efficiency of soil, water, light and other natural resources.
Article first time published onWhy does high input farming destroy soil?
Soil compaction is caused by heavy farm machinery use and tilling when soils are too wet; compaction has become an increasing problem as farm equipment has gotten increasingly heavier. Compaction leads to poor water absorption and poor aeration which further lead to stunted root growth in plants and smaller yields.
What is meant by specialized farming?
Specialized Farming- The farm from which 50% or more income is derived from a single enterprise viz. crops, livestock, dairy, poultry, etc., such farm is called specialized farm, and farming is called specialized farming.
What is the green revolution in agriculture?
Ray Offenheiser: The Green Revolution was the emergence of new varieties of crops, specifically wheat and rice varietals, that were able to double if not triple production of those crops in two countries.
What do you mean by Leisa farming approach explain with suitable examples?
The LEISA concept seeks to optimize the use of locally available resources by maximizing the complementary and synergistic effects of different components of the farming systems. External inputs are used in a complementary way. … No-till vegetable systems lire feasible using reduced herbicide rates to kill cover crops.
What is meant by organic agriculture?
“Organic agriculture is a holistic production management system which promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity. … Consumers take a conscious decision on how their food is produced, processed, handled and marketed.
What is integrated farming give example?
An example of integrated farming could be fish and livestock cultivation along with general farming practices which support each other. The fishes can be fed with the residuary materials of farms such as leaves, stalks or other waste products. … The silkworm pupae and other wastes can then be used to feed the fish.
Who is known as father of organic farming?
The British botanist Sir Albert Howard is often referred to as the father of modern organic agriculture, because he was the first to apply modern scientific knowledge and methods to traditional agriculture.
What depends heavily on external and chemical inputs?
Farming pattern depends heavily on external and chemical inputs It relies on the optimal use of natural processes. Focus of agricultural development & research .
Who invented biodynamic farming?
Biodynamic agriculture developed out of eight lectures on agriculture given in 1924 by Rudolf Steiner (1861−1925), an Austrian scientist and philosopher, to a group of farmers near Breslau (which was then in the eastern part of Germany and is now Wroclaw in Poland).
Which type of farming improves the soil fertility?
Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose …
What is differences between heia and Leia?
Because of its access to external resources, HEIA may tend more towards the use of accelerating technologies and management, whereas small-scale LEIA tends to adjust continuously to local conditions.
What is crop diversification?
Crop diversification is intended to give a wider choice in the production of a variety of crops in a given area so as to expand production related activities on various crops and also to lessen risk.
What is a low input system?
Low Input Farming Systems (LIFS) seek to optimise the management and use of internal production inputs (i.e., on-farm resources) and to minimise the use of production inputs (i.e., off-farm resources), such as purchased fertilisers and pesticides, wherever and whenever feasible and practicable, to lower production …
What are 3 important inputs for agriculture?
The important inputs are seeds, fertilisers, machinery and labour. The outputs from the system include crops, wool, dairy and poultry products. Some of the operations involved are ploughing, sowing, irrigation, weeding and harvesting.
What agricultural crop is most profitable per acre?
Bamboo is one of the most profitable crops to grow per acre. It can bring in lots of revenue, but the catch is it takes about three (3) years for the bamboo to get “established” once planted.
What is the most profitable crop for small farm?

- Landscaping trees and shrubs. …
- Bonsai plants. …
- Japanese maples. …
- Willows. …
- Garlic.
Which crop gives highest yield?
The most planted crops throughout the world are wheat and maize (corn). Rice and soybeans are other key staples. However, these are all relatively low yielding and do not make enough revenue per tonne of product produced. The highest yielding crops are sugar cane, sugar beet, and tomatoes.
What is Relay cropping?
Relay cropping is a method of multiple cropping where one crop is seeded into standing second crop well before harvesting of second crop. Relay cropping may solve a number of conflicts such as inefficient use of available resources, controversies in sowing time, fertilizer application, and soil degradation.
What is land utilization index?
Cultivated land utilization Index ( Chuang, 1973 ) is calculated by summing the products of land area to each crop, multiplied by the actual duration of that crop divided by the total cultivated land times 365 days.
What is intercrop vegetable farming?
vegetable farming The system of intercropping, or companion cropping, involves the growing of two or more kinds of vegetables on the same land in the same growing season.
What is the most fertile soil in the world?
Found in Ukraine, parts of Russia and the USA, mollisols are some of the world’s most fertile soil. This type of soil includes black soils with high organic content.
